The Organization of the Petroleum Exporting Countries (OPEC) was unable to agree on a new production quota. However, Saudi Arabia promised it won’t significantly boost production to corner more market share.

"We will be very gentle in our approach and make sure we don't shock the market in any way," Saudi Arabia's new energy minister Khalid al-Falih told reporters.

Saudi Arabia was backing a 32.5 million barrels per day (bpd) ceiling, which may be regarded as an attempt to repair relations with Nigeria, Algeria, Venezuela and other OPEC members. Some are reportedly angry with Riyadh for backing out of a production freeze deal between major crude exporters in April. Particularly, those countries whose economies were especially hard-hit by sliding crude prices.

"The Gulf Cooperation Council is looking for coordinated action at the meeting," a senior OPEC source told Reuters before the meeting, referring to Saudi Arabia and its allies Qatar, Kuwait and the United Arab Emirates.

Iran has been skeptical about any coordinated production ceiling, as it’s aiming to reach pre-sanctions level of production at 4 million (bpd). Iranian Oil Minister Bijan Namdar Zanganeh said that could be done “very soon,” but Iran sees no benefit in a collective quota, and wants an individual approach.

The deal between Saudi Arabia and Iran was even more unlikely due to the political crisis when Riyadh severed diplomatic ties with the Islamic Republic in January.
